There’s a strong trend in Product Management circles to insist that a good Product Manager must be strongly technical in addition to having strong marketing and communication skills. And while this approach is well-meaning, it often results in a weak Product Management role that merely supports Development rather than challenge it.

Now, that’s not to say that a Product Manager can be successful without some basic level of technical competency — in order to have honest discussions with development teams, and to build the trust and respect of those teams, you must have at least a passing familiarity with the technologies that are being used by that team. You have to at least know what the terminology means – not knowing the difference between MySQL and NoSQL at a very high level, for example, can and will negatively affect your ability to write effective user stories.
